An image forming material is provided in which a developer container containing a developer consisting of an electrically insulating organic material which is solid at ambient temperature and which may be liquefied on heating, and wherein colorant particles are dispersed in the material, is made as one with a photosensitive base on which to form an electrostatic latent image. With such image forming material, the developer required in the developing process is incorporated in the photosensitive base to permit image formation and storage by the electrophotographic process to be performed as easily as in so-called instant photography. When the outer size of the image forming material or that of the separated photosensitive base is of the 35 mm format slide size, the imaging material or the base may be attached directly to a slide projector or the like to permit the image information to be easily seen.
